david339933 thanks for the input. I see now Clause 6.3.1 explicitly says that threaded fittings shall still have wall thickness greater than that of the nominal wall of the pipe schedule. That would give justification to using the pipe wall thickness without thread allowance when calculating the...
Also I should probably clarify for others if needed: Most threaded fittings (elbows, crosses, tees, etc.) are governed by ASME B16.11 and use their system. But weld-on branch fittings (threadolets, weldolets, sockolets) aren't covered by ASME B16.11 but rather a different code MSS SP-97.
Looking to get clarity on something that has bothered me for years. There seems to be a giant misalignment that nobody talks about with threaded weld-on branch fittings (threadolets) per MSS SP-97 vs ASME B16.11's class system.
First, for most threaded fittings covered by ASME B16.11, Table 7...
Hello, I'm looking if somebody can advise me what the pressure-temperature ratings of MSS SP-114 Class 150 SS fittings are? I've heard that the equivalent P-T rating of threaded Sch 40 pipe should be used. Can anybody confirm if this is correct? I don't have access to the code and don't want to...
